The valves are China 1/4". The threads are machined terrible. On one side there was almost no peak on the thread. Finally got them to seal off by using ultra black gasket maker. Soon as I got it back together the lift valve on the driver side started leaking by. I ordered 3/8 smc valves yesterday. Gotta stop being cheap. The fittings are from Texas gauge in Houston. They have fittings that are quality copies of swagelok. They are decent price too.
